When our RINO governor in VT passed the mag limits last year, we just drive to NH or ME. All the new law did was encourage folks to stock up and keep buying.
When they voted for mag limits here in CO they grandfathered them. I bought enough mags to more than double what I had and they, being plastic, had time-date stamps on them. But it doesn’t really matter because mags with no time-date stamps could have been made at any time so ... prove they weren’t pre-ban! lol
In addition a majority of CO Sheriffs said then that they would not enforce any new gun laws. My Sheriff included.
For anyone who still wants mags just buy them out of state and if they have time-date stamps make sure they pre-date the ban. Suck it, libs, we’re not letting you push us any further.
